T0 all 'whom it may concern.:

Y Be it known that LENOCH RECTOR, a citif zen of the United. States,residing in the borough of Manhattan of the-city of New 1. York, intheState of New York, have invented certain vnew and. usefulImprovements in Steam-Generators, of which the following is aspecification.n My invention relates particularly to gen erators adaptedto produce steam under relatively high pressure and consists in the newl and novel features of construction and comt parts hereinafter set for@and claimed. c j.

In the accompanying drawings: Figure 1 is a side elevation in section ofa steam generator embodying my invention. F ig. 2 represents a plan viewof the same partly in section. Fig.. 3 represents a plan view partly in.section of another form of my improved steam generator. Fig. "4represents a side elevation partly in section of a generator mbodyingthe construction indicated in i 3. i

.'tlgfhe steam is generated by heat supplied' from, a burner 1,indicated diagrammatically, of any desired construction to supply alarge number of heatunits and is preferably arranged at the bottom of acasing 2 vwhich may be formed of or lined with any suitable insulating'materialsuch as asbestos 2a, the said casingbeing provided atits topwith an outlet 3 for the gases of combustion.

' The generator 4' preferably comprises a receptable, which ispreferably made in two parts, one of said parts preferably being a baseplate 5 of any desired section, and the other part being .a dome 6secured to the base'plate in anysuitable manner as by the Screws 7 or bybeing welded thereto. v

Secured to the base plate are a plurality O-f projections 8 which extendinto the'gen erating chamber or water space of thev generator. Saidprojections are preferably conical in shape and maybe formed integrallwith the base plate if desired, or the same may be secured thereto inany suitable man-V ner ,as by being provided with threaded stems 9'engaging in a tapped socket 10 provided in the base plate. If desired aplurality of radial ribs 11 may be provided extending between the'successive projections thus dividing the projections into a pluralityof sections, the said sections however bei ing in communication witheachother adjalevelv of the generator. lThe steam is con-.

ducted from-the generator by a suitable pipe 14 which communicates withthe top thereof.

In order to increase the heating capacity the side walls of thegenerator may be provided with aplurality of corrugations or ribs 15.The inside of the generator walll may be also provided with dependingribs or flanges 16 which extend downwardinto the generator chamber.-Preferably also the bottom of the base plate is provided with aplurality of hollow conical shaped projections 17 to increase theheating surface.

While generatin steam the water is not permitted to rise a ove the topsof the projections extending into the generating cham'- ber but isnormally kept a considerable vdistance below the top thereof. The projections or extensions actasheat conveyers and produce a continuouscirculation of the water which is contained in the small communieatingcompartments formed by the bases ofthe adjacent projections. The steamwhich is formed on the bottom tends to follow the metal and risesalongside vthe projections projections the friction of theqsteam tendsto carry particles of the Water with it-thus producing a' constantmovement or circula tion. By means of this construction an eX- tremelyvsimple and efficient generator is provided which can be made fromrsimple castings and with very little -fitting or packing of any kind.The eiiiciencyis extremely high owing tothe very large-amount of heatabsorbing `and radiating surface relative to the total quantity of watercontained in the generator at any one time and owing Valso to thecontinuous' circulation -of thewaterv 'lit may be used to heat Wateror4for any other similar purposes. If it is usedfsolely for heating water,it is no* necessary to main-1 tain the water level below the tops orapenesY of the projections, but the water may en' tirely fill thechamber. lln this case also, as in the generation of steam, theprojections serve as circulation producing means and induce and maintaina constant circulation within the generating chamber, thus facilitatingthe absorption of heat. lt is obvious also that various changes withinthe knowledge of those skilled in the art may be made in the detailsthereof Without departing from the spirit of the invention provided themeans set forth in the following claims be employed.

l claim as my invention: 1 f

l. A generator comprising `a generating chamberl having a plurality ofprojections extending from-the bottom thereof and tern minating withinthe generating chamber at a point above the water level of thegenerator.

2. ln a generator the combination with one of the walls of thegenerator, of a plurality of circulation producing projections extendingabove the-normal water level of the generator and' terminating withinthe generator slightly above the normal water level thereof. v

. 8. ln a steam generator comprising a generating chamber, a pluralityof conical v shaped projections extending partly in the water and partlyabove the normal water level of said generating chamber and terminatingwithin the generating chamber.

4l. ln a steam generator comprising a generating chamber, thecombination'of a plurality of projections terminating within thegenerating chamber and extending partly in v the water and'partly abovethe normal water level, and means for admitting water near the base ofsaid projections.

5. ln a Ysteam generator, the combination with a bottom plate having aplurality of -vertical projections, of a plurality of radial ribsextending from the center of said plate Y toward the circumference ofthe generator to divide said plate into a plurality of sections,saidsections having communication with each other adjacent to the wallofthe generator.

6. ln a steam generator comprising a base and a cap portion securedtogether-to form a generating chamber, a plurality of projectionsextending upward from the base plate into the generating'chamber andterminat ing within the generating chamber, and a plurality ofprojections extending down ward from said cap portion into the generHating chamber and terminating above said projections.

7. lln a steam generator comprising a base plate and a vcap portionsecured together to. form a generating chamber, a plurality ofprojections secured to the base plate extending into the generatingchamber and terminating above the normal water level, inlet pipe forsupplying water at the .base of said projections and below 'the normalwater level of the chamber, an outlet pipe secured to the cap portionand means secured to the base plate for increasing the heating surfacethereof.

48. lin a generator the combination `with one of the walls of thegenerator, of a plurality of circulation producing projections extendingabove the normal water level of 'the generator and terminating withinthe generator slightly above the normal water level thereof, the exposedheating surface of the projections above the water level increasingas'the water level is lowered at a greater rate than the rate oflowering of the Water level.

9. A generator comprising ay generating chamber having heat carryingprojections extending from opposite sides of one of the walls thereof,the external projections adapted to be subjected to the direct heat froma heating means and the internal projections-terminating within thegenerating chamber at a point above the water level in the generator. jj

l0. A generator comprising a generating chamber having a plurality ofprojections extending from the bottom thereof and terminating within thegenerating chamber at a point above the water level of the genera torand conical heating projections extendn ing from the exterior side ofsaid bottom.
